The invention relates to a rear wheel cover inner plate assembly and a preparation process thereof, a white vehicle body and a vehicle, the rear wheel cover inner plate assembly comprises an integrated rear wheel cover inner plate body, and a plurality of first reinforcing ribs and second reinforcing ribs are arranged on the rear wheel cover inner plate body; the first reinforcing ribs and the second reinforcing ribs are transverse reinforcing ribs and located on the two sides of the rear wheel cover inner plate body in the X direction respectively, and the multiple first reinforcing ribs and the multiple second reinforcing ribs are distributed in the Z direction at intervals. The first reinforcing ribs are convex ribs, the second reinforcing ribs are different in width, the cross section of each second reinforcing rib is an arc-shaped concave curved surface, the two ends of each second reinforcing rib extend in the X direction, and transition curved surfaces are formed between the two ends of each second reinforcing rib and the rear wheel cover inner plate body. Development of molds and tool clamps can be reduced; according to the integrally-formed rear wheel cover inner plate assembly, the redundancy of welding edges of a traditional rear wheel cover inner plate is reduced, the number of sub-assemblies is reduced, then the product manufacturing procedure is shortened, the accumulated error of a size chain is reduced, and therefore the precision of the rear wheel cover inner plate assembly is improved.

    本发明涉及一种后轮罩内板总成及其制备工艺、白车身和车辆,该后轮罩内板总成包括一体式后轮罩内板本体,后轮罩内板本体上设有多道第一加强筋和第二加强筋,第一加强筋和第二加强筋为横向加强筋且分别位于后轮罩内板本体X向两侧,多道第一加强筋和第二加强筋分别沿Z向间隔分布;第一加强筋为凸筋,多道第二加强筋宽度不一,第二加强筋的横截面为弧状凹曲面,第二加强筋的两端分别沿X向延伸并与后轮罩内板本体之间形成过渡曲面。本发明能减少模具和工装夹具的开发;一体成型的后轮罩内板总成降低了传统后轮罩内板焊接边的冗余,减少了分总成数量,进而缩短产品制造工序,减小尺寸链累计的误差,从而提升后轮罩内板总成的精度。
